Theoretical Physics

Researchers in the Fermilab Theoretical Physics Department advance the field of particle physics.

We are curious!

What makes up the Universe? What is Dark Matter? Why are Neutrinos so light? Do they violate CP? What sets the electroweak scale? Are there forces of nature we do not know of? Are there Sterile Neutrinos? How can we extract the most information from the LHC? What are the properties of the Higgs Boson? What can we learn for flavor and precision tests of the Standard model? Why is there more matter than anti-matter?

Working in concert with the experimental program, we pursue the major physics drivers of the field, including the Higgs boson, neutrinos, dark matter, and new theoretical frameworks. We develop and provide leading theoretical tools based on lattice QCD and perturbative QCD. We provide a uniquely stimulating environment for postdocs and students, and a hub for the U.S. particle theory community.
